Test values and control module connections for Popular




Scope

Values and instructions for testing the voltage levels of the control modules are found under the relevant headed sections.

Remember:


• Observe the conditions set for testing and use common sense when assessing the results.

• The test values presented apply when the ignition is in the ON position unless otherwise stated.

• First make sure that the control module is receiving power and that it is grounded.

• Then check all the sensor inputs and signals from other systems.

• Finally, check the control module outputs. Remember that the test values do not indicate whether the module is working.

• If a test value is incorrect, consult the wiring diagram to trace which leads, connectors and components should be checked more thoroughly.

• The specified test values refer to those obtained with calibrated Fluke 88/97.

• Test values in % (+) and ms (+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse duration readings should be used. The (+) symbol indicates a positive trigger pulse, TRIG+.
